Can I jailbreak the iPhone 5?

I have the iPhone 5.It's currently running IOS 7 beta 2.

I have been told that I can't backdate to 6.1.2 after I have upgraded, which is obviously a shame, I even went into my hosts folder and deleted the line about Apple to try and bypass the 3194 error from iTunes.

IPhone 3g not connecting to itunes at all?

I went to connect my iphone 3G to itunes this evening, had this phone over a year now and have had no trouble connecting it before, but tonight it won't connect at all. It makes two beeping noises when I plus it in, but it doesn't show up on itunes or my computer. I have tried charging it, and that works fine, no problems with charging just connecting to my computer. I have uninstalled itunes, reinstalled it and i have googled it for the past 2 hours but nothing works. Any advice? I have also tried restarting my computer, but that doesn't work. I'm on windows by the way, not mac or anything.

When it turned on, i noticed that it had a water stain beneath the screen! My camera is super foggy too! I put it in a bag of rice but that didn't help get the water out.

I also tried pressing the home button and the power button at the same time for 10 seconds, it didn't work. It keeps on showing the apple logo again and again.
